Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a vertical roof structure.

[0002]

2. Description of the Related Art Conventionally, as an exterior structure in which the surface of a building appears to be almost flat, the actual construction is 3-316.
No. 26 and JP-A-5-86695 have been proposed.

This type of exterior structure has a structure in which fixing tools such as screws and bolts are directly passed through the outer plate when the side edges of the left and right adjacent outer plates are connected to each other or mounted on the base. .

By the way, when such an exterior structure is applied to a roof, since the roof plate is formed to be long and has a large size in the flow direction of the roof, heat in the longitudinal direction is changed due to temperature change due to weather change or the like. Since the amount of expansion and contraction is large, therefore, when the roof plate is directly fixed with screws like the above-mentioned exterior structure, the screw holes will expand or the roof material will be distorted, resulting in poor waterproofness and appearance performance. It may decrease.

Further, the fixing portion is covered with a cover member in order to prevent rainwater from entering through the screw holes, but it is difficult to completely waterproof the roof of this kind having a flat surface. Yes, water leakage from the enlarged screw holes to the inside is inevitable.

Further, in the case of forming a roof surface by connecting the fixed-length vertical roofing boards in the flow direction, the waterproof structure of the connection part becomes complicated in order to waterproof the connection part in the flow direction. Also occurs.

The present invention has been made in view of such conventional problems, and a main object thereof is to provide a vertical thatched roof structure which is structurally reliable against thermal expansion and contraction and is excellent in waterproofness and appearance performance. To do. In addition, the waterproofness is secured when the roof plate is directly fixed with screws, etc., or when the fixed-length roof plate is used, it is directed to the indoor side against water intrusion from the connection part in the flow direction. The purpose is to prevent water leakage.

[0008]

In order to solve the above-mentioned problems, as the invention of claim 1, a support member is arranged on the lower ground of the roof, and a vertically-roofed roof plate is formed by folding down both side edges thereof. A vertical roof structure fixed to the support member via the engaging portion, the support member is composed of a lower support member and an upper support member, and the upper support member is slid in the flow direction with respect to the lower support member. It is movably attached, and at least one side edge engaging portion of the vertical roofing plate is fixed to the upper supporting member.

As a second aspect of the present invention, the lower support member of the above invention is provided with a running water space having a cross-sectional shape that is open upward along the flow direction.

Further, as a third aspect of the present invention, a water leakage prevention plate having a substantially corrugated cross-sectional shape when viewed from the flow direction is provided between the support members adjacent to each other in the column direction, and the side edges thereof are the support members. It was arranged so as to face the running water space.

[0011]

According to the first aspect of the present invention, since the upper supporting member is slidable with respect to the lower supporting member fixed on the base, the heat of the roof material engaged with the upper supporting member is increased. The upper support member slides in response to expansion and contraction and allows deformation, so that the roof material is not damaged.

Further, according to the second aspect of the present invention, even if rainwater enters through holes such as screws, it is caught by the running water space and discharged toward the eaves. There is no such thing as a leak.

Further, according to the third aspect of the present invention, since the continuous waterproof structure including the running water space of the support member and the water leakage prevention plate is formed between the roof plate and the base, the roof plate is fixed in length. Even if the structure is made by connecting in the flow direction, the water that has entered from the connection part is surely guided to the running water space,
Therefore, it is not necessary to make the connecting portion in the flow direction have a complicated waterproof structure.
